Audi & Volkswagen MK6 (GTI, A4, Q5 & More) Oil Separator - Features, Symptoms, And Product Review

Blog Feature

The 2nd and 3rd generation turbocharged two-liter Audi and Volkswagen engines feature a crankcase ventilation system (PCV) that is crucial to your engine's performance. If your breather/oil separator is failing, VW offers an updated genuine breather replacement. 

Although Volkswagen/Audi doesn't consider the PCV system a regular maintenance system, it's well known that these parts fail quite regularly. The symptoms are easily diagnosed as other failures, however, the PCV system should always be checked early on in the diagnostic process as it's easy to replace/repair and the parts are affordable.

Another option instead of replacing your oil separator is deleting your PCV completely and replacing with a catch can. Depending on the make and model of your vehicle, we recommend 034Motorsport's oil catch can kit. This kit is designed to prevent oil from depositing in the intake manifold and intake valves, resulting in drastically reduced carbon buildup and extended life of the intake manifold flapper assembly.
